- Scope
- This standard specifies the conventional method for analyzing the specific activity of natural or artificial radionuclides in soil using high-resolution semiconductor or NaI(T1) γ-ray spectroscopy. This standard applies to the specific activity of radionuclides in soil analyzed by gamma spectrometer in the laboratory. The count rate of the sample to be tested is less than 105 cpm, and the activity should be higher than the detection limit of the spectrometer.
